Johannes Kepler said that IF the planetary orbits are elliptical,
THEN that would explain the measurements that Tycho Brahe
spent his whole life collecting.
Isaac Newton said that IF gravity works the way he thought it does,
THEN the planetary orbits have to be elliptical.
But neither Kepler nor Newton could ever say that the orbits are REALLY ellipses.
Both of their statements are 'only theories', just like the theory of evolution.
They have never been proven.
Kepler discovered that the orbit of each planet is an ellipse rather than a circle.

It was Kepler who discovered that the planets orbits are elliptical.
ellipses.
Kepler's 1st law states that the orbits of the planets around the sun and makes an ellipse. This is taught in astronomy.
Johannes Kepler
Kepler's observations supported the fact that the plants orbit in an ellipse. He wrote the Laws of Planetary Motion stating all planets orbit the sun and all planets orbits are elliptical.

It was Kepler who discovered that the planets orbits are elliptical.
Kepler realised the planets orbits are not circles; they are ellipses.
Johannes Kepler.

Johannes Kepler determined that planets move in elliptical orbits around the sun in the early 17th century. His observations and mathematical calculations led to the formulation of his three laws of planetary motion.
Tycho Brahe, the eccentric Danish recluse, kept records of his observations that later enabled Kepler to establish the elliptical orbits of the planets.
That was Tycho Brahe who lived on an island near Copenhagen and employed the great Johannes Kepler as his mathematician.

No, Johannes Kepler is best known for describing the laws that dictate how orbits work. The Kepler planets were discovered by the Kepler telescope, a spacecraft named in his honor.
